7054721cf9 ath79: enable UART in SoC DTSI files
The uart node is enabled on all devices except one (GL-USB150 *).
Thus, let's not have a few hundred nodes to enable it, but do not
disable it in the first place.

Where the majority of devices is using it, also move the serial0
alias to the DTSI.

*) Since GL-USB150 even defines serial0 alias, the missing uart
   is probably just a mistake. Anyway, disable it for now so this
   patch stays cosmetic.

Apply this to 21.02 as well to remove an unnecessary backporting
pitfall.

6f96a4d043 ath79: remove model name from LED labels
Currently, we request LED labels in OpenWrt to follow the scheme

  modelname:color:function

However, specifying the modelname at the beginning is actually
entirely useless for the devices we support in OpenWrt. On the
contrary, having this part actually introduces inconvenience in
several aspects:

  - We need to ensure/check consistency with the DTS compatible
  - We have various exceptions where not the model name is used,
    but the vendor name (like tp-link), which is hard to track
    and justify even for core-developers
  - Having model-based components will not allow to share
    identical LED definitions in DTSI files
  - The inconsistency in what's used for the model part complicates
    several scripts, e.g. board.d/01_leds or LED migrations from
    ar71xx where this was even more messy

Apart from our needs, upstream has deprecated the label property
entirely and introduced new properties to specify color and
function properties separately. However, the implementation does
not appear to be ready and probably won't become ready and/or
match our requirements in the foreseeable future.

However, the limitation of generic LEDs to color and function
properties follows the same idea pointed out above. Generic LEDs
will get names like "green:status" or "red:indicator" then, and
if a "devicename" is prepended, it will be the one of an internal
device, like "phy1:amber:status".

With this patch, we move into the same direction, and just drop
the boardname from the LED labels. This allows to consolidate
a few definitions in DTSI files (will be much more on ramips),
and to drop a few migrations compared to ar71xx that just changed
the boardname. But mainly, it will liberate us from a completely
useless subject to take care of for device support review and
maintenance.
To also drop the boardname from existing configurations, a simple
migration routine is added unconditionally.

Although this seems unfamiliar at first look, a quick check in kernel
for the arm/arm64 dts files revealed that while 1033 lines have
labels with three parts *:*:*, still 284 actually use a two-part
labelling *:*, and thus is also acceptable and not even rare there.

41cc7edc15 ath79: move dts-v1 statement to ath79.dtsi
The "/dts-v1/;" identifier is supposed to be present once at the
top of a device tree file after the includes have been processed.

In ath79, we therefore requested to have in the DTS files so far,
and omit it in the DTSI files. However, essentially the syntax of
the parent ath79.dtsi file already determines the DTS version, so
putting it into the DTS files is just a useless repetition.

Consequently, this patch puts the dts-v1 statement into the parent
ath79.dtsi, which is (indirectly) included by all DTS files. All
other occurences are removed.
Since the dts-v1 statement needs to be before any other definitions,
this also moves the includes to make sure the ath79.dtsi or its
descendants are always included first.

a99614a44f ath79: consistently use "info" label for default-mac partition
The tp-link safeloader devices typically contain a partition
"default-mac" which stores the MAC addresses. It is followed by other
partitions containing device info, like

  {"default-mac", 0x610000, 0x00020},
  {"pin", 0x610100, 0x00020},
  {"product-info", 0x611100, 0x01000},

In DTS, we typically assign a 0x10000 sized partition for these,
which is mostly labelled "mac" or "info". In rarer cases, the
partitions have been enclosed in a larger "tplink" or "config"
partition.

However, when comparing different devices, the implementation appears
relatively arbitrary at the moment.
Thus, this PR aims at harmonizing these partitions by always using
the name "info" for the DTS partition containing "default-mac".
"info" is preferred over "mac" as we never just have "default-mac"
alone, but always some other device-info partitions as well.

While at it, this also establishes a similar partitioning for the
few devices where the "info" partitions are part of a bigger
unspecific "config" partition or similar.

Besides the harmonization itself, this also allows to merge a few
cases in 11-ath10k-caldata.

635f111148 ath79: drop and consolidate redundant chosen/bootargs
In ath79, for several SoCs the console bootargs are defined to the
very same value in every device's DTS. Consolidate these definitions
in the SoC dtsi files and drop further redundant definitions elsewhere.

The only device without any bootargs set has been OpenMesh OM5P-AC V2.
This will now inherit the setting from qca955x.dtsi

Note that while this tidies up master a lot, it might develop into a
frequent pitfall for backports.

646d95c374 ath79: add support for TP-Link Archer C60 v3
TP-Link Archer C60 v3 is a dual-band AC1350 router,
based on Qualcomm/Atheros QCA9561 + QCA9886.

It seems to be identical to the v2 revision, except that
it lacks a WPS LED and has different GPIO for amber WAN LED.

Specification:

- 775/650/258 MHz (CPU/DDR/AHB)
- 64 MB of RAM (DDR2)
- 8 MB of FLASH (SPI NOR)
- 3T3R 2.4 GHz
- 2T2R 5 GHz
- 5x 10/100 Mbps Ethernet
- 6x LED, 2x button
- UART header on PCB

Flash instruction (WebUI):
Download *-factory.bin image and upload it via the firmwary upgrade
function of the stock firmware WebUI.

Flash instruction (TFTP):
1. Set PC to fixed IP address 192.168.0.66
2. Download *-factory.bin image and rename it to tp_recovery.bin
3. Start a tftp server with the file tp_recovery.bin in its root
   directory
4. Turn off the router
5. Press and hold reset button
6. Turn on router with the reset button pressed and wait ~15 seconds
7. Release the reset button and after a short time the firmware should
   be transferred from the tftp server
8. Wait ~30 second to complete recovery

While TFTP works for OpenWrt images, my device didn't accept the
only available official firmware "Archer C60(EU)_V3.0_190115.bin".

In contrast to earlier revisions (v2), the v3 contains the (same)
MAC address twice, once in 0x1fa08 and again in 0x1fb08.
While the partition-table on the device refers to the latter, the
firmware image contains a different partition-table for that region:

name           device            firmware
factory-boot   0x00000-0x1fb00   0x00000-0x1fa00
default-mac    0x1fb00-0x1fd00   0x1fa00-0x1fc00
pin            0x1fd00-0x1fe00   0x1fc00-0x1fd00
product-info   0x1fe00-0x1ff00   0x1fd00-0x1ff00
device-id      0x1ff00-0x20000   0x1ff00-0x20000

While the MAC address is present twice, other data like the PIN isn't,
so with the partitioning from the firmware image the PIN on the device
would actually be outside of its partition.
Consequently, the patch uses the MAC location from the device (which
is the same as for the v2).

88aead0a66 ath79: fix swapped LAN/WAN MAC address for Archer C60 v1/v2
The MAC addresses for lan/wan are swapped compared to the vendor
firmware. This adjusts to vendor configuration, which is:

lan   *:7b   label
wan   *:7c   label+1
2.4g  *:7b   label
5g    *:7a   label-1

Only one address is stored in <&mac 0x8>, corresponding to the label.

This has been checked on revisions v1, v2 and v3.

231dc26867 treewide: remove dts-v1 identifier from DTSI files
The "/dts-v1/;" identifier is supposed to be put once at the beginning
of a device tree file. Thus, it makes no sense to provide it a second
time in to-be-included DTSI files.

This removes the identifier from all DTSI files in /target/linux.

Most of the DTS files in OpenWrt do contain the "/dts-v1/;". It is
missing for most of the following targets, though:
mvebu, ipq806x, mpc85xx, ipq40xx

This does not touch ipq806x for now, as the bump to 4.19 is close.

f4026ad24d ath79: DTS file style update and harmonization
This applies several style adjustments that have been requested in
recent reviews to older DTS files. Despite making the code base more
consistent, this will also help to reduce review time when DTSes
are copy/pasted.

Applied changes:
- Rename gpio-keys/gpio-leds to keys/leds
- Remove node labels that are not used
- Use label property for partitions
- Prefix led node labels with "led_"
- Remove redundant includes
- Harmonize new lines after status property
- Several smaller style fixes
